Overview

  • Independent measurements show the standard iPhone 17 hits about 27–28W over USB‑C across a wide range of Apple chargers, up from roughly 23W on iPhone 16.
  • Pro models can briefly peak near 36W, but Apple rates the entire iPhone 17 lineup to reach 50% in about 20 minutes when paired with a suitable charger.
  • ChargerLAB recorded a 29W peak using Apple’s latest MagSafe Charger, and Apple says sustained MagSafe wireless charging can hold around 25W.
  • Apple’s 40W Dynamic Power Adapter (60W max burst) is now on sale in the U.S., Canada, China, Japan, Mexico, Taiwan, and the Philippines.
  • Cable choice matters for performance, and the USB‑C port also supports standard accessories such as external displays, storage, mics, Ethernet, with iPhone 17 Pro offering up to 10Gbps USB‑3 data when used with the right cable.
